This application claims the benefit of U.S. Provisional Application No.61/860,041 filed Jul. 30, 2014

FIELD OF THE INVENTION

This invention relates to napkins and bibs, and is more specificallyrelated to a napkin or bib having an adhesive for holding the napkin orbib in place on clothing of a user.

BACKGROUND OF THE INVENTION

Napkins and bibs are used to prevent foreign substances from soilingclothing during certain operations. For example, napkins and bibs areplaced over the chest of a user to prevent food from soiling the user'sclothing during dining.

A common use of napkins and bibs is to protect a patient's clothingduring dental or other medical operations. A napkin or bib may be placedover a patient's chest during dental procedures so that dentalmaterials, liquids, blood and the like do not soil the patient'sclothing during the procedure.

When the user of a napkin or bib is seated so that the user's chest isin a substantially vertical position, which includes dental chairs thatrecline up to 30 degrees, the napkin or bib must be held in place sothat it does not fall away from the user's clothing. A neck band may beattached to one side of the bib, and to an opposite side of the bib, andpassing behind the neck of the user to hold the napkin or bib in place.Such neck bands have included chains having clips, such as alligatorclips, to hold the napkin in place. However, it is time consuming toattach the neck band to the napkin. A reusable neck band, such as achain, should be sanitized after each use in a medical setting, which istime consuming and expensive. More recently, a paper neck strap withadhesive on both ends has been developed. However, fastening the strapis extra work for the dental staff, and necessitates the userrepositioning his or her head for attachment.

Other napkins or bibs have permanently attached neck bands, which may bemade of paper or other materials from which the napkin or bib is made,and which are disposable. However, it is somewhat cumbersome to placethe neck band over the patient's head so that the napkin is held inplace.

Other devices use adhesives to secure the napkin or bib to the user'sclothing. These devices have an adhesive layer on the napkin or bibwhich is covered by a peel away strip. The peel away strip is covered bya release tab. The dental or medical assistant must pull the release tabaway from the adhesive prior to positioning the napkin or bib on thepatient. This task is time consuming, requires particular dexterity, andcreates trash that must be disposed of prior to attachment of thenapkin.

There is a need for a napkin or bib having adhesive for positioning andholding a napkin or bib against a patient's chest, but which does notnecessitate the use of released tabs or similar coverings for theadhesive that must be removed and disposed of when positioning thenapkin or bib.

SUMMARY OF THE INVENTION

The present invention is a napkin or bib that protects clothing of theuser. The napkin or bib has an adhesive that holds the napkin or bib inposition on the user's clothing. Adhesive is present on one side of thenapkin or bib, but the adhesive is not covered by release tabs that mustbe removed from the napkin and disposed of prior to use of the napkin.

FIG. 2 is a sectioned view of the napkin, showing the layers of thenapkin and the adhesive layer.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

The terms “napkin” and “bib” are used interchangeably herein. The napkinor bib 6 may be formed as a sheet of material that may be placed over auser's clothing, and generally in the chest area, to protect the user'sclothing during certain procedures, such as, but not limited to, dentaland medical procedures. The napkin may be made of most any material thatmay be formed into sheets, including paper materials, plastic materials,or combinations thereof.

In a preferred embodiment, the napkin 6 is formed in a multiple ply,such as a two-ply, construction. If two plies are used, one ply 12 maybe formed of a water absordbing material, such as paper material, whichmay be a pulp tissue, with the other ply formed of a water repellantmaterial 10, such as plastic, which may be, or comprise, polyethylene. Acommon nomenclature for construction of bibs is: 1 ply paper/1 ply poly;2 ply paper/1 ply poly; and 3 ply paper/1 ply poly. The paper may bethree layers or plies, each of which is very thin, such as paper fromwhich facial quality tissue made. The resulting sheet of material thatforms the napkin may therefore be a laminate, with each layer havingsubstantially the same height and width as each other and as theresulting sheet of material.

The polyethylene (plastic) layer may be contoured as shown in FIG. 2, orit can be flat. The polyethylene layer may be embossed on the inner(facing the user) layer to better control liquids absorbed by the paper(or pulp) surface and transmitted to the polyethylene surface. Thetextured surface created by embossing helps to reduce sliding of the bibor napkin on the user's chest area.

The water repellant side is positioned against the user's clothing, andthe opposite, paper side faces outwardly to absorb liquid or semi liquidmaterial, with the plastic or water repellant side preventing theabsorbed material from reaching the user's clothing. In a preferredembodiment, the construct is embossed. An embossing pattern 8 helpsretain liquid materials on the surface of the napkin, a smooth surfaceincreases the likelihood that materials will run downwardly, and off ofthe surface, and to the user's clothing below the napkin. This embossingpattern also prevents the napkin from sliding on the user's chest area.The embossing pattern, as demonstrated in FIG. 2, may be formed inchannels, or peaks and valleys.

An adhesive area is present on the napkin. The adhesive area is presenton the water repellant or plastic side of a napkin when a multiple plynapkin is used. The adhesive area is positioned on the inward side ofthe napkin, that is, on the side that faces the user's clothing. Theadhesive area is also preferred to be positioned at an upper portion ofthe napkin, usually on opposite sides and beneath the neck area of thenapkin, as shown in FIG. 1.

In a preferred embodiment, the napkin 6 comprises at least two adhesiveareas 2, 4 that are spaced apart from each other, and are present nearthe top of a napkin on the inward (inner) side, or water repellant side,of the napkin with a two-ply construction as described above isincorporated. FIG. 1.

In a preferred embodiment, the adhesive areas 2, 4 comprise a substrate14 having a first side and a second side. The adhesives on each side mayhave different adhesion qualities. A first adhesive 16 attaches thesubstrate to the inward facing side of the napkin. The first adhesivethat secures the substrate to the napkin may be a liquid or pasteadhesive such as QUICK GRIP brand (Beacon Corp.) adhesive that containssynthetic polymers (30%), Tackifier (20%), Acetone (30%), and Hexane(20%). The first adhesive has sufficient strength to permanently adherethe substrate to the dental napkin so that the substrate is not easilyremoved. If the napkin is a multiple ply napkin, the first adhesive willtypically be present on the plastic ply that is positioned against thepatient's clothing. In general, the first adhesive should havesufficient adhesion qualities so as to cause the napkin to tear if thesubstrate is pulled away from the napkin after the first adhesivecompletely sets.

In another embodiment, the substrate has a first adhesive 16 and asecond adhesive 18 that are present on opposite sides of the substrate14, such as by coating the adhesive onto the substrate. The firstadhesive may have an adhesion measurement that is higher than the secondadhesive. The first adhesive has sufficient adhesion to hold thesubstrate firmly against the plastic coated side of the napkin, it againbeing preferred that adhesion is sufficient such that tearing of thenapkin may be experienced if the substrate is removed from the napkinafter the substrate is secured on the napkin. The first adhesive ispreferred to have adhesion of about 35 ounces or greater. The adhesionof the second adhesive is sufficient to hold the napkin against clothingas required by the invention.

An example of a substrate that provides acceptable adhesion in someembodiments is 3M SCOTCH brand Permanent Double Sided tape, which hasadhesion on one side of the substrate of about 35 ounces, and on theother side, about 31 ounces. The higher adhesion side is pressed againstthe napkin, and the opposite side with lower adhesion is used to attachthe napkin to clothing. The substrate of the tape described may be acellulose acetate, and the adhesives may be a synthetic acrylic. Thesubstrate may be about 3-4 mils. thick, with a tensile strength of 15pounds per square inch or more. Adhesion measurements referred to hereinare according to ASTM-D3330 for adhesion to a standard steel panel.

It is observed that while a higher degree of adhesion is preferred onthe side of the substrate that attaches to the napkin, the bond of anadhesive coated substrate to the plastic coated side of the napkin isinherently higher than the bond of the adhesive to clothing. The surfaceof the plastic coated napkin provides better adhesion than mosttextiles, even if the adhesion measurement of the adhesive is the same.Accordingly, a double sided tape with adhesion of not less than about 35ounces on one (inner) side and not less than about 31 ounces on theother (outer) side provides acceptable results. Adhesives having thesame adhesion on both sides may be acceptable as long as the goals ofthe invention are met. The adhesive that attaches the substrate to theplastic side of the napkin may have an adhesion of more than about 35ounces, although the upper limit of the outer side that attaches to auser's clothing cannot be so high that the adhesive will damage clothingor be difficult to remove from the user's clothing.

Alternatively, the substrate 14, which may be plastic, and may bepolyethylene or poly propylene, may be heat sealed to the plastic ply ofthe napkin, which may be polyethylene or poly propylene. The heat sealis sufficiently strong so that the plastic of the one-ply, two-ply orthree-ply napkin will tear if the substrate is pulled away from thenapkin. The heat seal may be accomplished in one embodiment by heatsealing around the perimeter of the substrate 14 areas to attach thesubstrate(s) to which the second adhesive is applied to the plastic plyof the napkin.

The substrate 14 may have a second adhesive 18 with different adhesionqualities than the first adhesive on the opposite side of the substrate.The substrate is a barrier between the adhesives, and is preferred to bea plastic material, such as plastic substrates used for packing tapes,that prevents migration of the adhesives through the substrate,particularly when the first adhesive is in the liquid or semi-liquidstate. The substrate should also not be dissolvable, or materiallysoftened, by the adhesives. The substrate may be a polypropylene film,and may be a pressure sensitive, water-based acrylic tape. The substratemay be formed of 3M SCOTCH brand storage tape #3650, which also providesthe second adhesive, and has an adhesion of 20 ounces. The adhesive isdescribed as long lasting, and has good tolerance for exposure to theatmosphere.

The second adhesive 18 may have less adhesion than the first adhesive16. The second adhesive, when used in the first adhesive area 2 and thesecond adhesive area 4 near the top of the napkin, as shown in FIG. 1,is sufficient to allow positioning of the second adhesive againsttextile materials of which clothing is formed, and to hold the napkin inplace on clothing for the user's torso, usually in a generally verticalposition, while the user is seated.

The adhesion qualities of the second adhesive are also such that thenapkin can be peeled away from the user's clothing by ordinary manualeffort without damaging the textile of which the user's clothing isformed. The second adhesive is preferred to have an adhesion of about 25ounces to about 40 ounces, and more preferably, about 28 ounces to about38 ounces with the preferred use of two spaced apart adhesive areas eachhaving an area of less than about 1.5 square inches.

In one embodiment, an acrylic repositionable adhesive that is equivalentto the adhesive used on 3M POST-IT BRAND SUPER STICKY NOTES is used asthe second adhesive.

Typically, light manual pressure, such as rubbing or pressing the secondadhesive will enhance adhesion of the second adhesive to clothing,without creating adhesion that will damage the clothing. Adhesion of thesecond adhesive is such that it will not materially damage cotton, wool,and polyester, silk or linen, and will not leave visible (to the nakedeye) adhesive behind when the napkin is removed. Pulling away a fewfibers from the clothing by the adhesive is not deemed as materialdamage, but adhesive that makes a structural change to clothing that isvisible to the naked eye is deemed to be material damage.

The second adhesive may be coated on a polypropylene film, and thesecond adhesive may be an acrylic adhesive. The second adhesive may havea degree of adhesion of about 25 ounces to about 40 ounces, and morepreferably, about 28 ounces to 38 ounces to hold the napkin withrelatively small areas of adhesive. If the second adhesive is coated onthe napkin, then no first adhesive is used, since no substrate isattached to the napkin by the first adhesive.

The size of areas 2, 4 may depend of the degree of adhesion of thesecond adhesive. If the areas are large, then a second adhesive withless adhesion may be required. It is possible to cover as much as theentire inner surface of the napkin, or substantially the entire innersurface of the napkin, and next to the patient or user, with the secondadhesive. The area comprising the second adhesive may be a single area,rather than two areas in some embodiments.

In another embodiment, the second adhesive is coated over the liquidrepellant ply of the two ply napkin at about the areas 2, 4. In thisembodiment, no first adhesive or substrate 14 is used. The secondadhesive 18 is coated directly on the liquid repellant ply 10 of thenapkin.

In the present invention, it is preferred that the adhesive areas do nothave a covering for the adhesive, which must be peeled away prior touse. It is undesirable to require the operator, particularly in a dentalor medical setting, to peel away the tabs, which is time consuming,requires particular dexterity, and creates undesirable trash in thesetting.

To accomplish the required characteristics, the second adhesive has agreater affinity for the substrate 14 than for the plastic or otherwater repellant material that is present on the napkin. Accordingly, ifthe napkin is folded for packing and shipping, and is unfolded prior touse, the second adhesive may contact the inward surface or layer that isa plastic material, and slightly adhere to the surface of the napkin.However, the napkin is easily pulled apart for use, and the secondadhesive that is coated or otherwise applied to the substrate 14 retainssufficient adhesion for attachment to the user's clothing, and willperform to hold the napkin in place as required.

However, in another embodiment, receiving areas 22, 24 may be formed onthe napkin as shown in FIG. 1. The receiving area or areas correspond tothe adhesive area or areas 2, 4 so that when the napkin is folded, suchas along the line demonstrated by the dotted line in FIG. 1, the secondadhesive contacts the receiving areas. The receiving areas may be formedcoating the receiving areas with a material commonly used with pressuresensitive articles like bumper stickers, or by adhering a very glossypaper to the areas, or by adhering a paper that is coated with a releaselayer that has little affinity for the adhesive that contacts it. Thereceiving areas may have a silicone material that receives, butreleases, the adhesive. Alternatively, a wax material like the waxsurface of wax paper may be used to form the outer surface of thereceiving areas.

The adhesive releases from the receiving areas when the napkin isunfolded, with little or no adhesive remaining on the receiving areas,so that the efficacy of the adhesive for the clothing is substantiallyuninhibited. The surface of the receiving areas facilitates release ofthe second adhesive, which is coated on the substrate. These receivingareas are permanently bonded to the surface of the napkin, such as byheat or by an adhesive having strong adhesion qualities, like the firstadhesive. Other known methods for permanently bonding the receivingareas to the napkin may be incorporated, or the napkin may be coated orotherwise provided with a material to form the receiving areas, with thematerial having surface qualities that are similar to the peel awaymaterial used with bumper stickers, which may be silicone, and whichwill easily release the second adhesive. If the second adhesive iscoated on the plastic ply, the use of receiving areas may be moreimportant, so that the second adhesive will have superior affinity forthe plastic ply but will not stick when folded.

The receiving areas 22, 24 may be a tape having an adhesive for holdingthe tape against the napkin, with the opposite side having no adhesiveand forming the release layer. The adhesion of the adhesive in thisembodiment is preferred to be 20 ounces or greater. A substrate thatwill provide the receiving areas is 3M SCOTCH brand “Magic Eco Friendly”tape, which has a synthetic acrylic adhesive with 20 ounces adhesion.The substrate for the receiving areas may be coated with a wax orsilicone or other release layer for releasing the second adhesive.

In the case of 1, 2 or 3 ply paper, combined with a 1 ply plastic, suchas polyethylene, to form the napkin as described herein, the liquidpolyethylene ply 10 of the napkin receives the adhesive areas when thenapkin is folded, such as during manufacturing or preparation forpackaging, by folding the napkin along the line demonstrated by thedotted line in FIG. 1. The adhesive areas 2, 4 may slightly stick to theliquid polyethylene ply during storage and shipping of the foldednapkin. The properties of the second adhesive 18 are such that when thenapkin is ready for use, the adhesive areas are easily peeled away fromthe part of the liquid polyethylene ply against which they contact whenthe napkin is folded, and the adhesive areas are available for use. Noseparate peel away covering is present or needed, since the portions ofthe liquid repellant ply against which the adhesive areas are folded actto protect the adhesive portions from dirt or other contaminates fromthe time of manufacturing until the napkin is ready for use.

The receiving areas 22, 24 may be used to retard undesired adhesion. Theliquid repellant ply 10 may be plastic as described herein.

In use, the device is positioned so that the inward side attaches to theuser's clothing to protect the user's clothing from soiling from foreignmaterials. There are no peel-away tabs present. Typically, the napkinwill be folded, and it is only necessary to unfold the napkin with thesecond adhesive easily peeling away from the area of the napkin that isopposite the adhesive areas, which may be receiving areas, or whichsimply may an area of the napkin.

The adhesive areas 2,4 are present on the side of the napkin thatcontacts the user/patient's clothing. In one embodiment, marks ofcontrasting color is applied to the opposite, outer facing side of thenapkin and directly opposite the adhesive areas 2,4. It is preferred torub and or press the adhesive areas against the user from the outwardlyfacing side of the napkin to insure contact with the user's clothing,and proper adhesion of the adhesive areas with the user's clothing. Themarks identify, from the outwardly facing side of the napkin, thelocation of the adhesive areas, so that pressure can be applied to thoseadhesive areas. The mark may be applied by printing, and may be adesign, letters, numbers or other indicia, including decorative indiciathat indicates the location of the adhesive areas.

When used in dental operations, the napkins typically have dimensions ofapproximately 11″ to 15″ width and 16″ to 20″ height. The overallsurface area of the napkin is preferred to be not less than 175 squareinches.

Each adhesive area formed by the substrate and the first adhesive andthe second adhesive is preferred to have an area of about 1″ to 2″ widthand 0.50″ to 1.25″ height. The aggregate area of the adhesive area ispreferred to be not less than about 1.5 square inches, and preferablynot less than about 2.0 square inches. It is preferred that at least twospaced apart adhesive areas are used, each positioned near an upperportion of the napkin, but well-spaced apart. Each adhesive area ispreferred to be not less than about 1.00 square inches, and up to 2.5square inches when used with the preferred adhesion. It is preferredthat the receiving areas, if used, have a slightly largely dimensionthan the adhesive areas.

It is preferred that the width of the adhesive areas exceed the height.The adhesive areas in most embodiments will be rectangular in shape. Theadhesive areas are preferred to be positioned near the top of thenapkin, and spaced apart from the top and the left and right edges,respectively, of the napkin. More particularly, it is preferred thatfirst adhesive area is positioned in the top one-third of a surface areaof the material forming the napkin and on a left half of the sheet ofmaterial. The first adhesive area is spaced apart from a left edge ofthe sheet of material. Similarly, the second adhesive area is preferredto be positioned in the top one-third of the surface area of the sheetof material forming the napkin and on a right half of the sheet ofmaterial. The second adhesive area is spaced apart from a right edge ofthe sheet of material.

The napkin should be positioned to cover the clothing of the wearer thatis worn on the upper torso. Typically, this means that the top edge ofthe napkin is positioned up to the neck of the wearer, and across theshoulders. The first adhesive area and the second adhesive area arepreferred to be positioned below (spaced apart from) the top edge of thenapkin, so that the adhesive areas contact the wearer's clothing that isbelow the clavicle, and preferably, above the top rib of the wearer.This part of the anatomy usually provides a generally flat andrelatively firm area against which the adhesive areas can be secured.

When two spaced apart adhesive areas are used of the preferred adhesionand with the preferred surface area, the napkin may be quicklypositioned by applying pressure to each of the relatively small areas toattach the napkin to clothing. A quick rub to apply pressure to eachadhesive area will affix the napkin adequately for use. The location ofthe adhesive areas will be known to the operator, such as a dentalassistant, from use. The adhesive areas are generally less flexible thanthe rest of the napkin, and may be felt by the operator from theopposite side of the napkin. Location of the adhesive areas may beassisted by the optional indicia which are visible from the opposite,and outer, side of the napkin. The use of relatively small areas ofadhesive provides a napkin that is easier to attach, and easier toremove than a napkin larger areas of adhesive, and when used withadhesives having proper degrees of adhesion, presents less risk ofdamage to clothing.
